UNITED STATES ATENT FFKCEO TOOL FOR MAKING GLASS PITCHERS, 81.0.

SPECIFICATION forming part of Letters Patent No. 233,672, dated October26, 1880.

Application filed April .14, 1880.

To all whom it may concern:

Be it known that I, WILLIAM HALEY, of the city of Pittsburg,Pennsylvania, have invented a new and useful Improvement in the Processof Making Pitchers, &c., which improvement is fully set forth in thefollowing specification, reference being had to the accompanyingdrawings.

Similar letters of reference indicate correspondin g parts.

This invention relates to improvements in the manufacture of glasspitchers and other articles in glassware; and it consists in the novelconstruction and arrangement of a snap, which is used for the purpose ofholding a pitcher or other articles of glassware, and at the same timefacilitate the trimming and forming of the same, as will be hereinaftermore fully explained.

In the annexed drawings, to which reference is made, fully illustratingmy invention, Figure 1 represents a side view of the apparatus used incarrying out myinvention. Fig. 2 designates an edge view of same. Fig. 3is a view of the pitcher before it has been formed and trimmed. Fig. 4is a view, showing the pitcher after it has been formed and its edgestrimmed.

By reference to the drawings, A designates the snap proper consisting ofa hollow standard, A, at the upper end of which, secured thereto or casttherewith, is a cross-head, B,

having pivoted therein the arms 0 of the jaws or former O, which formeris provided on its outer face with cars a for the reception of the upperend of acrooked arm, D, passingthrough a slot in cross-head B, andhaving their lower ends connected to a link-bar, b. The inner end of thelatter is pivoted to a sliding sleeve or collar, 1), on the standard A,and is operated by means of a coil-spring, c, placed within said hollowstandard and encircling a plungerrod, E. The upper end of said springcbears against a shoulder, d, in the standard A, and the lower end ofsaid spring rests against the shoulder d on the plunger-rod E, asclearly shown in Fig. 1. Through the upper end of the rod aforesaid, andpassing through the sleeve or collar 1), is a pin, 6, playing verticallythrough a slot, f, in the hollow standard A, which regulates themovement or stroke of the plunger-rod, and thus prevents the sleeve orcollar b from becoming misplaced.

(Model) The crooked arms D are further provided near their center withslots f, passing through the same 5 and also through the cross-head Bare pins g, for the purpose of serving as a guide for the "ertical andvibrating movement of the crooked arm D aforesaid.

The operation of my invention is as follows: To insert a pitcher orother article of glassware in the former or jaws O 0, this isaccomplished by pressing the rod E, thereby causing the sleeveorcollar 1) to move vertically on the standard A, taking therewith thelink-bar b, at the same time drawing the lower end of the arms D Dinwardly, which has the effect of causing said arms to swing on pins gg. By such movement above mentioned the jaws or formers are separated oropened for the introduction of articles of glassware. The reaction ofthe spring 0 causes the jaws G to close and embrace the pitcher or otherarticle, and securely holds the same while bei n g formed and trimmed.

It will also be observed that the inner faces of the jaws O O are shapedto correspond with the upper end or neck of the pitcher.

It will further be seen that the surplus glass usually adhering to allarticles of glassware after being blown, as shown in Fig. 3 of thedrawings, is placed in the snap, and the upper end is sheared or trimmedoff to conform with the shape of the pivoted arms 0 G and jaws C O, asat h h. The flaring-tool may then be introduced to impart the properfinish or shape to the upper end of the article to be flared. Theflaring is done by pressing a piece of wood of the proper shape againstthe inner surface of the upper edge of the article, and pressing thesame against the faces of the jaws O O, in the usual manner well knownto glass-blowers.

After the body of the pitcher has been formed and the mouth flared, asdescribed, a pressed handle or handles, or other desirable projectionsto be used in taking hold of the pitcher or like article, are attachedto the body thereof by the ordinary method of cutting a little hot glassand dropping the same on the placeswhere the pressed handle has to beunited to the body. of the article.

I am aware that snaps have been made and used of various constructions,and that blowpipes have been attached to snaps for blowing and formingglass vessels requiring handles,

&c., and therefore do not claim what is contained therein; but

What I do claim is 1. In a snap for forming glass pitchers, thecombination of arms 0 (J, with thejaws O G, pivoted to the cross-head B,and provided with the arms D I), connected to the sliding sleeve orcollar 1) by links I), and operated byineans of the coil-spring 0, forthe purpose of opening and closing said jaws, as and for the purpose setforth.

2. The method herein described of shaping the neck and mouth of glasspitchers and other articles of glassware, by reheating the same inthctsnap A, the jaws G C of which correspond to the form to he impartedto the article,then trimming and flaring of the same to conform to theshape of thejaws, as specified.

WILLIAM HALEY.
